Measuring the God Particle
The electromagnetic and hadron calorimeters [left] make up the center of the 49-foot-high, 69-foot-long Compact Muon Solenoid, an instrument designed to probe the nature of mass itself by finding the elusive Higgs boson particle. Scientists believe the Higgs boson causes mass to exist, and have nicknamed
it "the God particle." These calorimeters measure the energy of particles that fly off after a collision.
